Detailed Description

Triangular element which represents fibre tension.

This element considers the forces along the z axis when tension is applied along the length of the yarns. It is assumed that the yarn tensile stress remains constant and can be set as a parameter. The tensile force applied along the z axis is linearly proportional to the slope at that point. If the slope is 0 then the force in the z direction is 0 (it will all be in-plane, but this force is not simulated). If the slope is non-zero then there will be a z component to the force propertional to the slope.
